a = Complex(1, 4)                         # => Complex(1, 4)
a.real                                    # => 1
a.image                                   # => 4

b = Complex(1.5, 4.25)                    # => Complex(1.5, 4.25)
b + 1.5                                   # => Complex(3.0, 4.25)
b + 1.5*Complex::I                        # => Complex(1.5, 5.75)
